RS485 Anti-Interference Device Passive 485 Filter RS485 Data Protector RS485 Communication Data Iso

Industrial-grade -sized electrical terminals provide more stable and reliable contact. Anti-EMI frequency converter PLC interference to protect data. Loaded on the signal to reduce surges, resist RMI electromagnetic interference, and protect from being burned. The 485 anti-interference device can be connected in series on the signal line. The passive RS485-422 broadband anti-interference isolator can work in strong interference environments and ensures normal communication of control data. Product application: The product has exquisite design, simple wiring and easy use. It is widely used in fields such as industrial monitoring, civil PTZ monitoring and industrial equipment control. Features: Operating range can be as wide as industrial-grade temperatures of -45 to +85 degrees No photoelectric type temperature drift and additional power supply noise No need for additional power supply and passive optocoupler that replaces power-stealing methods No secondary interference caused by the use of power supply due to RS485 photoelectric isolator Passive RS485/422 isolator with excellent 12ns transient response Standard RS485/422 line impedance matching, return loss 18DB Low insertion loss, less than 0.8DB Operating temperature range: -45 degrees to +85 degrees Material: plastic+metal colour: black+blue Package Contents: 1 x RS485 anti-interference device Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
